Title: Method for coating sand core
Inventor: OTAKE TSUYOSHI
IPC: C10N40/36
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of a gas venting hole and the lowering of jointing precision of a combined core by applying a coating material on the whole surface of the sand core after sticking a stick inhibitor for the coating agent to a position receiving the adverse effect with the coating material. SOLUTION: The material 30 having water repellency is stuck on the position receiving the adverse effect with the coating agent in the sand core 10, i.e., each of gas venting holes 12 so as not to stick the coating agent and thereafter, the coating agent is applied on the whole surface of the sand core 10. In the case of sticking the stick inhibitor 30 to the sand core 10, the opening part sides of the gas venting hole 12 in the sand core 10 are pressed to the solid stick inhibitor 30, and the sand core 10 is reciprocatedly moved. By this method, the stick inhibitor 30 is stuck in the state of closing the opening parts of the gas venting holes 12. Thereafter, the ordinary coating is executed to the surface of the sand core 10. By this method, the coating material is not stuck to the opening part of the gas venting hole 12 or is melted by drying heat and removed.

Title: Rubber composition
Inventor: YOSHIDA NORIFUMI
IPC: C08K3/00
Filed: 1986-12-25
Abstract: PURPOSE:To obtain a rubber composition having excellent bloom-preventive effect independent of the thermal history of processing and giving a vulcanized rubber without causing the lowering of physical properties, by adding a specific amount of a crosslinking agent composed of sulfur and a sulfur-butadiene copolymer. CONSTITUTION:The objective composition can be produced by compounding a rubber with a crosslinking agent consisting of sulfur and a sulfur-butadiene copolymer. The amount of sulfur in the crosslinking agent is <=1pt.wt. per 100pts.wt. of the rubber or below the solubility of sulfur in the rubber. Sulfur necessary for crosslinking (usually 0.1-10pts.wt.) and exceeding the solubility of sulfur (about 1pt.wt. at room temperature or thereabout) is replenished with the above copolymer.

Title: Up-conversion laser material
Inventor: MIURA SEIKI
IPC: C03C3/32
Filed: 1993-12-08
Abstract: PURPOSE:To realize up-conversion laser oscillation at a temperature approximate to a room temperature, by constituting up-conversion laser glass in the stat of microspheres, confining light, and making the microsphere itself work as a resonator. CONSTITUTION:Microspheric glass is fluoride glass, chloride glass, bromide glass, and chloride fluoride glass. The grain diameter is in the range of 50-2000mum. The content of rare earth element ions is in the range of 50-5000ppm. From a pumping light source 1, 800nm laser light is converged by using a lens 2, and the end of a rare earth added microsphere 3 is irradiated with the laser light. It was recognized by the existance of oscillation spectrum and a threshold value (100mW) that 550nm laser light is obtained as the result of <4>S3/2 <4>I15/2 transition by the <4>I15/2 <4>I9/12 excitation and <4>I11/2 <4>F7/2 excitation of Er<3+>. Hence up-conversion laser oscillation at a room temperature is realized in the glass composition which is hard to turn fibrous or the glass composition which causes no oscillation when a fiber is not constituted.

IPC: H01L29/732
Filed: 1988-12-07
Abstract: PURPOSE: To increase the drop of forward diode voltage by preparing an emitter area acting as a cathode in a diode, a collector area and a base area acting as an anode and a floating collector area and a base area for increasing the voltage drop of the diode. CONSTITUTION: The voltage drop controlling diode is formed by an NPN transistor(TR) structure having a single emitter 18, two collectors 17, 19 and two bases 21, 22. A metallic layer 25 short-circuits a collector contact area 17 to a base contact area 21 to form an anode in a diode. A metallic layer 26 forms a contact with the emitter contact area 18 and acts as the cathode of the diode. Additional base-collector short circuit is formed by a metal 27 and acts as a floating contact part. Thus the voltage of the emitter of the NPN TR is lower than that of a normal reference diode only by about 60mV due to voltage dividing operation to be executed by resistors 41, 43 in addition to resistors 34, 36, 37, 47.
